SHOWER-BATH STALL.

Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed July 14, 1916. Serial No..109,210.

To all whom it may concern: I

Be it known that I, WALTER J. KoHLER, a citizen of the United States, and resident of Sheboygan, in the county of Sheboygan, and State of Wisconsin, have invented new and useful Improvements in Shower-Bath Stalls, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention has for its object to provide in a single-piecestructure an enameled iron shower bath stall, adapted to be let into a recess in the wall where it will constitute an enamel lined inclosure free from joints including sides, back, and bottom, and a front with a contracted doorway, all without seams or oints.

The object of the invention is to produce a more sanitary structure by eliminating the necessity for cement seams at the meeting edges of the sections of a sectional structure, thus making it possible 0 con tinue the glazed enamel lining as an uninterrupted and unbroken polished surface eX- tending throughout the interior of the stall, making it easy to clean and pleasing in its appearance.

Another object of the invention is to avoid the necessity for accurately fitting together the sections of such a sectional structure, making the entire stall member in a single integral casting which may be easily set up and readily tiled into the wall of the room if desired.

The more important object of the invention is to produce a shower bath stall of onepiece constructifi soas to be watertight and prevent the leakage of water therefrom even though cracks may develop in the walls in which it is embedded.

With the above and other objects in View the invention consists in the shower bath stall as herein claimed and all equivalents.

Referring to the accompanying drawings, in which like characters of reference indicate the same parts in the different views:

Figure 1 is a central sectional view of a shower stall constructed in accordance with this invention.

Fig. 2 is a plan view thereof;

Fig. 3 is a front view thereof with a portion broken away;

Fig. 4 is a sectional plan view;

tially rectangular shape in cross section,

with rounded corners merging with the reversely bent edges of a doorway 11 at the front thereof extending from a threshold 12 which stands some distance above the level of the floor to a top piece 13 at the extreme upper edge of the casting. Around the remainder of the upper end of the casting there is an outwardly turned flange 14 70 adapted to be tiled into the lining of the dome or ceiling of the stall. The raised threshold forms a basin of the lower part of the shower stall which is drained through a central outlet opening 15 toward which the bottom gently slopes, and suitable feet 16 project downwardly from the bottom to rest on the floor and support the casting.

Formed in the sides 11 of the doorway, just above the cross-piece 13, are semi-circular lugs 17 forming open hearings to receive the ends of a metal pipe forming a curtain rail 18 from which a curtain may be suspended to cover the doorway.

If desired, the threshold 12 of the doorway may be provided with a depending apron 19 continuing the enameled metal sur face to the floor, as shown in Fig. 6.

The shower bath stall of this invention is pleasing in its appearance, as the enameled surface thereof is continuous throughout, but the more important result of its integral structure is the absence of cement joints or creases between overlapping or abutting enameled metal sections, which creases or joints would be liable to open and permit the leakage of water in the event of the walls settling and developing cracks. In most shower stalls constructed of cement or sectional tiling, or shower receptors with tile walls, the danger is always present that if the house settles in any manner cracks will develop, permitting of leakage and the possibility of more or less damage to the finishings and the furniture of the rooms below. With the single-piece structure of this invention the development of such cracks is impossible.

The basin-like formation at the bottom of the shower stall permits of water being accumulated therein to a desired depth.

The surrounding flanges when tiled into the wall and floor present a neat and finished appearance incorporating the shower stall into the walls of the room.

What I claim as new and desire to secure by Letters Patent is:

A shower stall, comprising a hollow metal single-piece casting substantially rectangular in cross section with side walls, front and rear walls, and a bottom wall connected by rounding corners, the upper edges of the casting being turned outwardly to form a horizontal flange for tiling into the wall, and the front wall being provided with an opening forming a doorway-with its threshold raised above the bottom wall to form a basin of the lower part of the casting, a depending apron at the front of the threshold adapted to be tiled into the floor, the side edges of the doorway being turned outwardly to form vertical flanges in the plane of the apron to be tiled into the walls of the room, and a vitreous enamel coating covering the interior of the casting as an uninterrupted glazed surface extending over the horizontal flange and the vertical flanges and the apron, there being a drain opening in the bottom wall toward which said bottom wall is inclined.

In testimony whereof I afliX my signature in presence of two witnesses.
